I consider myself reasonably tall. Don't get me wrong, I'm no giant. I'm just a little taller than average. My little brother, on the other hand, is real tall. About 6'5". I look up when I talk to him, but just slightly.
I met a guy today who is easily over 7 feet tall. That's right. He's enormous. I felt like I was looking straight up at him while we were talking. It was ridiculous. The standard joke with tall people is, "How's the weather up there?" But all jokes aside, this guy probably really does feel subtle changes in atmospheric pressure when he's not busy dodging low-flying aircraft. Standing next to him, I felt like a small child. Tiny. Seriously, like a preschooler. It was all I could do to not laugh during the conversation. I don't know what's wrong with me, but it's obviously something serious because all I could think was, "So what time is recess? I'm gonna hit up the monkey bars today!"
If you have never met someone this tall, do so immediately. Drive down to your local freak show and demand to see the tallest guy they've got. You're life might never be the same. Or it might. You really never know with these things.
